Period: Select a predefined time range from the drop-down list (for example, Last 24 hours or Last 30 days). Each
time range in this list refers to complete increments only, and does not include partially elapsed time increments. For
instance, Last 12 hours defines the 12 most recently complete hours, not including any time that has elapsed in the
current hour.
If you select Today, the report will cover the period starting at midnight of the current calendar day and ending at
the time the report is run.
